Copying from Wikipedia:
2000 years ago, the nation of Kouka was founded by the Crimson Dragon God (Hiryuu), who came down to Earth from the Heavens as a human, deemed the Crimson Dragon King (King Hiryuu). As a result, humans forgot about their god and became evil, seeking power. The Crimson Dragon King was eventually forced to fight against these humans, and just as he was about to be killed and the world was on the brink of extinction, four other Dragon gods, imbued with the dragon blood, joined his side as human warriors, and helped him. After clearing Kouka of evil, the Crimson Dragon King died. The four Dragon warriors mourned his death and walked separate ways from his castle, leaving the country to develop over the centuries into 5 Tribes: Sky, Earth, Water, Wind, and Fire. As countless generations flew by, this history became a famous founding myth.
2000 years later, the story commences with Yona, the sole princess of Kouka, ruled by her pacifistic father King Il under the Sky Tribe. Yona lives a lavish, sheltered life from the harrowing reality outside of the walls of the Crimson Dragon Castle, her only friends being her bodyguard Hak, general of the Wind Tribe, and Su-won, her crush of 10 years and the son of King Il's brother, Yu-hon. But contrary to this peaceful illusion, Kouka is once again on the verge of destruction and about to undergo a political upheaval.
A week before a party celebrating her sixteenth birthday, Su-won visits to pay tribute to her. Upon revealing to her father her intention to someday marry him, Yona is shocked and dismayed when King Il forbids her from choosing Su-won as a husband. On the night of her 16th birthday party, Yona visits her father's chambers again, determined to change his mind. Instead, she walks in on Su-won driving a sword through King Il's chest, revealing that he had planned a coup d'état and would become Kouka's next King. Yona and Hak become fugitives and are forced to flee to Fuuga, the capital of the Wind Tribe. Under the suggestion of Hak's adopted grandfather and prior Wind Tribe General Son Mun-deok, Yona and Hak search for a priest of several expelled from the Sky Tribe capital by Su-won's father, Yu-hon. The priest tells Yona about the Crimson Dragon King and four dragon warriors who unified the nation. Guided by the founding myth, Yona begins a journey to find these dragon warriors in order to survive and save her country.
